I know there is a program that completely constructs a header and makes each pipe just the length you need. You can program it for minimal bends or making the bends with longer then xx radius. Its very comprehensive but... i cant seem to find it...
Im using full CNC pipebending equipment. If i could find a program that will route them and at the lengths I want then all i have to do is send the data to the programer and out pops my header tubes completely mandrel and one piece.
Im working on some headers and I need to know how to bend and route the pipes for the pipe lengths. Iv seen of modeling software out there but I can't remember the company. Can anyone help me out?
Well you have the introduction of oxygenated air into the turbo header without injection which will cause a burn in the header. On the flip side if you eliminate the spark you have air and fuel introduced into the header. He already said he cant use nitrous.
Not being a 2 stroke expert or anything but the bottem mounted exhaust valve would cause some signifigant problems in ring wear. Also the flow of air is not instantanious.
The valve would have to be uncovered for a much longer time then just 10 degrees abdc. Also the way it works the engine...
That is such an odd description of a rotary.... heh
I was more talking about the posibilities of quarter speed double lobed cams.. or mayby quad lobe 1/8th speed. What are the fricitonal losses of cam bearings? Has anyone tested it? It seems a design like this would be limited by packaging...
Thats 4271 degrees F. You sure this really happened??? For it to instantaniously vaporize the entire cylinder in one stroke (what had to happend because the next stroke wasnt building heat) you would of had to have one REALLLY hot explosion in that cylinder. 6000+ I would imagine to permiate...

Those are all good basic titles that cover all the spectrum of performance engines.
Very simply all throttle assemblies are not treated equal. Depending on the attention to drivability by the manufacturer the throttle body will cause an inverted logrithmic effect. As the throttle increases numerically in degrees the effect on engine power will go down in perportion. at 50...
On PD intake manifold it would seem that a large plenum size would be pretty much meaningless because of the type of blower. THe smaller the better in this case? *to a point of not limiting flow to the runners.
Adding onto the last post... Some basics i left out... Bore is 3.503 stroke is 3.13. I havent cc`d any intake ports. Exhaust valve is a 32 mm flowing 230@400. Approxiamate id for intake ports, 1.85 ovalized. Valve train assembly is a roller follower setup with 1.8:1 rocker arms. Thats about...
Its the 3.0L Jag/mazda engine flows 270 cfm at .400 inches through a 35 mm valve. It pushes 230 all stock and 200 in torque at the brake. Im leaving the head alone and going for 8:1 compression ratio. Running an air water intercooler, all going into a 2200 pound lightened focus chassis with a...
Im actaully going with an autronic or motec fuel management system with staged injection. What I thought I could do for sensors is that I can mount small "vacuum" hoses from in behind the throttle plates of every cylinder into a small alumnium box thats centralized between them (making sure the...
I was wondering if it would be possible to run a blow through screw supercharger. It seems throttle response would be greatly enhanced by going to blow through ITB`s where positive pressure is waiting on the throttle plates to open. If not this a couple of large throttle plates on a sealed pre...
I think what most people experience from putting a bag of ice on the plenium, is that all map sensor cars have a intake air temp sensor on the plenium (mayby not all but alot)and it causes this sensor to read a lower temp and that sends the timing up a bit. Does increase power. I dont think...
I think one major reason power is down on lower compression engines is because the higher compression engine builds a higher vacuum in the intake tract at a lower piston degree after TDC(realistically a shorter distance from top dead center). The higher compression engine should generate...
I have no actaul experience with spraying/misting/squirting much of anything into a compressor assembly. If i were going to do it, Id just be careful to make sure its atomized reallllly well before it hits the assembly. Anything thats quite a bit heavier then the air will not spin in with the...
